macOS: Optionally flush sub-layers via sub-image copies of the backingstore
When we're flushing the backingstore to sub-views with their own layers
we don't want to pay the cost of uploading the whole backingstore to the
GPU in the case where we're dealing with a discrete GPU.
To work around this we make a copy of the appropriate part of the surfcace.
This results in additional copies of the data, and will need further
investigation to limit these.
